STAR TELECHELIC POLY LACTIC ACID IONOMERS AND PROCESS FOR SYNTHESIS THEREOF

摘要

ABSTRACT STAR TELECHELIC POLY LACTIC ACID IONOMERS AND PROCESS FOR SYNTHESIS THEREOF Polylactic Acid (PLA) is a promising material, on account of its biodegradability and biorenewablity. However its poor melt elasticity and low glass transition temperature limit its applicability. Thus there is a need to improve these properties. Star telechelic ionomers of PLA with no restriction on the number of ions that are incorporated in the ionomers are provided. The ionomers disclosed possess improved elastic modulus and are prepared from easily available substrates employing a simple process.
